Magnetic separator is used to recycle powdered granules to remove iron powder and other screening equipment. After the slurry flows into the tank through the feeding box, under the action of the water flow from the mine spray pipe, the ore particles enter the feeding area of the tank in a loose state. Under the action of the magnetic field, the magnetic mineral particles are magnetically aggregated to form "magnet clusters" or "magnet chains". The "magnet clusters" or "magnet chains" move to the magnetic poles in the pulp and are adsorbed on the cylinder. Since the polarities of the magnetic poles are alternately arranged along the rotation direction of the cylinder and are fixed during operation, the "magnet cluster" or "magnetic chain" will produce magnetic stirring phenomenon due to the alternating magnetic poles when the cylinder rotates, and become mixed The gangue and other non-magnetic minerals in the “magnet cluster” or “magnet chain” fall off during turning, and the “magnet cluster” or “magnet chain” that is finally attracted to the surface of the cylinder is the concentrate.

Ball mill is the key equipment for crushing materials after crushing. This type of ore grinding machine is equipped with a certain number of steel balls as grinding media in its cylinder. The ball mill is composed of a horizontal cylinder, a hollow shaft for inlet and outlet, and a grinding head. The cylinder is a long cylinder with a grinding body, which is made of steel plate, with steel lining plate fixed to the cylinder body. The grinding body is generally steel balls, which are packed into the cylinder according to different diameters and a certain proportion. It can also be made of steel. According to the particle size of the grinding material, the material is loaded into the cylinder by the hollow shaft at the feed end of the ball mill. When the cylinder of the ball mill rotates, the grinding body is attached to the cylinder liner and taken away by the cylinder due to the action of inertia, centrifugal force and friction. When brought to a certain height, it will be thrown down due to its own gravity, and the falling grinding body will crush the material in the cylinder like a projectile.
